Data

This dataset describes (a) concentrations of nutrients and related constituents, and (b) discharge in the lower Boise River (Idaho) and its primary tributaries for Water Years 1994 through 2023 and 1969 through 2024, respectively. Constituents include water column concentrations of suspended sediment, total phosphorus, dissolved phosphorus, orthophosphate as phosphorus, total nitrogen...

Data set includes field observed cover of several vegetation functional groups, e.g. annual herbaceous, perennial herbaceous, exotic annual grasses, perennial bunch grasses, shrubs, sagebrush shrubs, non-sagebrush shrubs, bare mineral soil, rocks, and litter. Additionally, if tree canopy was present within field plots, tree canopy cover was estimated, forest type recorded, and the number...

This data release presents multi-year ecosystem metabolism model outputs for Brownlee Reservoir at varying depths across three locations (River Miles 318, 300, and 286) along the Snake River. Data include field-collected model input data and model outputs of daily gross primary production (GPP), ecosystem respiration (R), and net ecosystem production (NEP). Field data were collected from...

We investigated male reproductive success of feral horses (Equus caballus) at Conger and Frisco Herd Management Areas (HMAs) in Utah, USA between 2017 and 2020. We collected data on male social status (harem stallion, lieutenant, tag, bachelor or in natal group) and group type (single male or multi-male) at both sites, and at Conger we additionally examined social interactions among...

Stream temperature data and streamflow data from headwater streams in the upper Snake River basin, Wyoming and upper Yellowstone River basin and Flathead River basin in Montana. These datasets were assembled to assess how stream temperature and streamflow in headwater streams deviates from downstream gages in order to better understand tools to estimate streamflow at a variety of...

These data were compiled to support ecosystem monitoring and management and to inform ecological transition probabilities and drivers. Objective(s) of our study were to produce maps of ecological states each year during 1986-2022 within two dominant ecological site groups (ESGs) in our study area. These data represent annual time series digital maps of ecological states in the Semiarid...

In cooperation with the Tennessee Wildlife Resources Agency (TWRA) and University of Tennessee Knoxville (UTK), the U.S. Geological survey (USGS) collected cyanobacterial toxin concentrations (i.e., microcystin, anatoxin, cylindrospermopsin, and saxitoxin) and water-quality field data at 4 sites on the Clinch River from November 2020 to December 2023. The goal for the sample data was to...

In cooperation with the Tennessee Department of Environment and Conservation (TDEC), the U.S. Geological Survey (USGS) measured cyanobacterial toxin concentrations (i.e., microcystin, anatoxin, cylindrospermopsin, and saxitoxin) and collected water-quality field data at 18 sites in North-central Tennessee from August 2022 to November 2024. Additionally, selected sites also were sampled...

These data consist of three primary types of products for managers of boreal toads in the Southern Rocky Mountains: 1) Re-constructed hydroperiods for historical breeding sites from LANDSAT imagery from 1985-2022 (SMA_hydroperiod_reconstruction.csv). This dataset was developed using a Spectral Mixture Analysis (SMA). 2) Current (1985-2022) and future (2040-2069) predictions of...

The Chesapeake Bay Hyper-Resolution Hydrography Database is intended to facilitate analysis of the landscape in the Chesapeake Bay watershed through identification of headwater and other low-order streams or drainage features (e.g. ditches) that, to date, may be absent from existing hydrography data products. A full description of the methodology and accuracy assessment is provided in...

This data release includes downscaled climate inputs and hydrologic outputs from 41 Basin Characterization Models (BCM) version 8 (v8), described in Flint and others (2021), with a 10 by 10-meter spatial resolution at monthly intervals from water years 1896 to 2023. Forty-one (41) models were developed for sentinel monitoring locations in Wildlife Areas and Ecological Reserves in...

This data release provides comprehensive results of monotonic trend assessment for long-term U.S. Geological Survey (USGS) streamgages in or proximal to the watersheds of Mobile and Perdido Bays, south-central United States (Tatum and others, 2024). Long-term is defined as streamgages having at least five complete decades of daily streamflow data since January 1, 1950, exclusive to those
